Hi Sabrina! Yes, I would cover it lightly with a sheet of wax paper and then something light such as a pillow case to start. Since this soap has ingredients that can heat up more easily, you probably don’t have to wrap it heavily. If you notice that it’s developing a crack down the middle, that means it’s heating too much, so you’d want to uncover it then so it can cool better. Good luck with your soap! :)
